Operational Workflow
This section describes the sequence of operation of the flushing methods that can be operated by using
AMC Flushing controllers.
The following is a description of the sequence of operation for each possible method without providing
the time duration of each stage in the described method. The actual time duration of each such stage
depends on the filter type selected by the technician during the installation of the controller.
Controlling a Battery of Filters:
A battery of filters consists of 1-6 or 1-12 filters installed on the same manifold and serves the same
water system where a single Flushing Controller controls the system. This arrangement allows a
sequential flushing process where only one filter flushes at a time and the filters are flushed one after
the other.
Note:
The maximal number of filters in a battery controlled by a single 6 solenoid controller is 6 where
neither Main Valve nor Delay Valve are configured, 5 where a Main Valve or a Delay Valve is
configured and 4 where a Main Valve and a Delay Valve are configured.
The maximal number of filters in a battery controlled by a single 12 solenoid controller is 12
where neither Main Valve nor Delay Valve are configured, 11 where a Main Valve or a Delay Valve
is configured and 10 where a Main Valve and a Delay Valve are configured.
A battery of filters without Mai n or Delay Valves:
Starting the flushing cycle:
l DP signal: Once a signal from the DP switch is received, the controller starts to count down the DP
delay time. If the signal remains present until the end of the countdown, a flushing cycle starts.
l Time parameter: By the end of each flushing cycle, the controller starts to count down the Time
between Flushes Parameter. Once this parameter is counted down to zero, a flushing cycle starts.
Note that if a flushing cycle is started by a different trigger (for example, a DP signal or manual com-
mand) the controller re-sets the countdown of the time between flushes parameter and starts to
count it again.
l Manual start: The user initiates a flushing cycle by pressing “Manual” button on the controller’s
keyboard.
The flushing cycle:
l Solenoid valve number 1 is switched on, the flushing of the first filter of the battery starts and the
controller starts to count down the Flushing Time parameter. Once this parameter is counted down
to zero the solenoid of the first filter is switched off and the process moves to the next stage.
l The controller counts down the “Between Filters Delay” parameter and once this count reaches
zero the controller switches on the solenoid of the second filter of the battery and starts to count
down again the Flushing Time parameter. Once the flushing process of the second filter is finished,
the controller counts again the delay between filters and starts the flushing of the next filter. This
process continues until the last filter is flushed and the flushing cycle is ended.
